Description

Technical Field

[0001] The utility model relates to the technical field of lamp radiators, in particular to an aluminum plate radiator for a lamp. Background Art

[0002] Electronic products are developing in the direction of high power, high integration and miniaturization, which leads to higher and higher operating temperatures of electronic devices. Insufficient heat dissipation capacity will cause the operating temperature of electronic devices to rise sharply, which will directly affect the performance, stability and service life of the devices. In order to solve the heat dissipation problem in these medium and low temperature environments, passive heat dissipation and active heat dissipation are currently used. Passive heat dissipation refers to heat dissipation by heat convection based on external conditions such as air and wind. This method depends on the external environment where electronic devices, LED lights and high-voltage wires are located. It is greatly affected by the environment, the effect is unstable, and the heat dissipation effect is poor; active heat dissipation mainly adopts the method of adding fans and increasing the heat dissipation area to achieve heat dissipation. This method is based on the principle of heat convection heat dissipation. Compared with passive heat dissipation, although it can greatly improve the heat dissipation effect, the radiator has problems such as heavy weight, large space occupation, energy consumption and noise generation, which is contrary to the development of miniaturization and lightweight of electronic products.
